Our bathroom is all original, probably build late 60's early 70's. We would like to redo it, but we don't plan on living in this house forever, so don't want to spend too much. Does anyone have experience with resurfacing tiles? Wondering if it is worthwhile with a bathroom this old, where some tiles will have to be replaced and the grout redone in some areas anyway. How durable is the spray they use? Getting a quote for the resurfacing on Saturday, so cost will play a big part - but if cost is similar between spraying and redoing the tiles, not sure which way to go! (Would be tiling myself) On the tiling note, if we strip off the old tiles for new, do we also have to redo any waterproofing?
